Mitt Romney is about to address the GOP presidential race in a surprise speech

Mitt Romney’s giving a surprise speech about the 2016 presidential race on Thursday.

The former governor of Massachusetts and 2012 GOP presidential nominee will address the Hinckley Institute of Politics Forum at the University of Utah in Salt Lake City on Thursday, per his office.

Romney has yet to endorse a candidate, although it was rumoured last month that he’d endorse Florida Sen. Marco Rubio. Rubio’s camp later denied those rumours.

In recent days, Romney has engaged in a back-and-forth with GOP frontrunner Donald Trump, whom he’s denounced for failing to distance himself from a Ku Klux Klan endorsement and for not releasing his taxes.

Trump has returned the criticism, saying Romney was one of the “dumbest and worst” Republican candidates to ever run for president.
